Wireless water leak detectors and shutoff valves
Features of Ajax automated water leak detection system
Automatic water shutoff
WaterStop remotely shuts off the water supply at the secured by Ajax facility. The device consists of a Bonomi shutoff valve and a powerful electric actuator with a control unit. WaterStop connects to the hub using the secure Jeweller radio protocol. With an internet connection, you can control the water shutoff valve from anywhere — Ajax apps allow you to check the device status and change the valve position remotely at any time.
WaterStop will automatically shut off the water in 5 seconds by LeaksProtect alarm. At the same time, all users, and the security company will receive a notification about the leak alarm and scenario activation. Water shutoff can also be configured by schedule or when the security mode changes.Learn more
Water leakage sensors in the security system
Flood sensors for alarms help prevent flooding in the guarded premises. With this device, the user learns about the leak, neutralizes the threat in time and saves the repair.
Where to install a flood sensor for an alarm
Since many buildings, residential or not, have plumbing, leakage sensors are used in any of their types.
The most common objects for installing flood sensors are swimming pools, saunas, houses and apartments, offices, places with a lot of electronic equipment that does not tolerate even minimal contact with water.
How the flood sensor works
The flood sensor is equipped with a pair of contacts that are responsible for analyzing the moisture level of a certain surface. Typically, these contacts are made of stainless material or copper, and the sensor housing itself is made of durable plastic.
The contacts are connected to the power supply, and to the input of the built-in comparator. When drops of water fall on the device, a current begins to pulsate from the positive wiring through the resistance. After that, the voltage on the second leg increases and passes the switching threshold. Then, by increasing the load, the flood sensor of the security system signals the detection of water.
How to choose a flood sensor for an alarm
To select a flood sensor for an alarm, you should contact a security company, whose specialists know best the required number of devices, their types and optimal places for the mounting.
Before installation, the installation engineer will calculate the layout of the flood sensors and check the device case for integrity. The absence of damage to the device affects its performance, so there should be no chips or cracks.
Flood sensor by Ajax
You can detect flooding in a guarded room from the first drops using the Ajax wireless flood detector. The device operates at a distance of up to 1300 m to the alarm control panel and does not require complex installation.
A wireless flood sensor is installed in places with an increased risk of flooding — in bathrooms, kitchens, laundries, etc.
The principle of operation of the flood sensor from Ajax
LeaksProtect wireless water sensor from Ajax detects flooding in the building from the first drops. The sensor is equipped with four pairs of contacts, and as soon as water gets on them, the system sends an alarm signal to users and the security company (a security system can be connected to the security company’s monitoring console if desired). When the water dries, the device will notify you.
The user can also control the solenoid valve via a relay. Thanks to this, the security system will automatically shut off the water before the arrival of emergency services.
Features of the wireless water leakage sensor from Ajax
The wireless water leakage sensor has the following features:
- The housing of the Ajax wireless water leakage sensor is protected from dust and moisture, they do not affect the performance of the device.
- Ajax flood detectors operate on pre-installed batteries for up to 5 years.
- No special tools are needed to install the sensor, it is enough to install it in the place of a possible leak: under the bathtub or sink. The compact size allows you to place the device in a hard-to-reach place.
- If the leakage is minor or if water gets on the contacts by accident, the security system’s wireless flood sensor will immediately alert users to dry out.
- In the event of a flood, the sensor can trigger an automatic water shutoff script that will block the water supply.
